Folks,
Perhaps you all have heard the news that Riccardo Giacconi, for his X-ray
work, and Ray Davis and Matoshi Koshiba, for their neutrino work,
have won the Nobel Prize in Astrophysics for 2002. The citation reads:
The Sun and all other stars emit electromagnetic radiation at different
wavelengths, both visible and invisible light, e.g. X-rays. In order to
investigate cosmic X-ray radiation, which is absorbed in Earth?s atmosphere,
it is necessary to place instruments in space. Riccardo Giacconi has
constructed such instruments. He detected for the first time a source of
X-rays outside our solar system and he was the first to prove that the
universe contains background radiation of X-ray light. He also detected
sources of X-rays that most astronomers now consider to contain black holes.
Giacconi constructed the first X-ray telescopes, which have provided us with
completely new -- and sharp -- images of the universe. His contributions
laid the foundations of X-ray astronomy.
Congratulations to Dr. Giacconi.
Clear skies,
Al
